Developer Options are located in Settings, under header General, all the way to the bottom & just above About Phone. If you don't see them, go into About Phone, in Software info, tap or click Build Number 7 times.

Turn on Automatic System Updates. So you no longer have to manually go into About phone, in Update center, then check for System Updates to get an OTA OS update.

Set WebView Implementation to your favourite variant of The Chrome browser, because this will only work for a Chrome browser. If you did, then you can even go into apps & uninstall updates from Android System WebView to free up storage space & disable it to free up ROM usage.

Turn on Enable multiprocess WebView. Your set app for WebView will run web content in an isolated & sandboxed process for improved performance & security when WebView is called upon by an app.

Under header Debugging, Set Logger Buffer Sizes to 64K per log buffer for improved performance. Even lower if your ROM has 32K or better, 8K.

Under header Debugging, Allow mock locations allows you to change the location information, making your phone think that it is in another location. You need a mock location app to spoof your GPS location with this setting.

Some Bluetooth audio devices do not work well with Android's Bluetooth absolute volume feature. Such as being too loud or having a lack of volume control. To fix this, under Header Networking, turn on Disable Absolute Volume.

Under header Input, you can turn on Show touches to see a visual feedback for touches on the screen. Keep it off if you don't need the visuals to help see or understand where & what you are touching.

Under header Drawing, set Window & Transition animation scale along with Animator duration scale to .5x . This will increase their playback speed. If you set those to off, that will actually completely turn off some needed visual effects for the software & apps to function properly.

Under header Hardware Accelerated Rendering, turn on Force GPU Rendering. This will enable hardware acceleration of 2D drawing for applications written without this by default.

You can use the shader MSAA 4x along with any shader in use by DraStic or with any Open Gles 2.0, or above, enabled app that doesn't already use it by default. By going into settings of your Android device. Within developer options. Underneath the header Hardware Accelerated Rendering, turn on Force 4x MSAA. This will cause a slightly higher battery drain, as any anti-aliasing shader does, & may cause an FPS decrease, depending on your device's hardware & software specifications. For low end devices or most cell phones this is best left off. For most high end devices such as flagship smartphones, video gaming console tablets & Android enabled TVs, specifically flagship phablet smartphones, Nvidia Shield tablets, & Nvidia Shield Android TVs with The Tegra X1 chipset, Force 4x MSAA will most likely not cause a frame rate decrease. This setting is best turned only on when you're going to be playing video games & turned off when you're not. As well as being able to manually set this setting on or off, if your device is powered off or powered off & restarted, including booted & hot booted, Force 4x MSAA will reset to off. To use it after that, you will need to set it again.

Under header Apps, Set Backround Process Limit to at most 4 background processes. It says Background Processes, but it's actually referring to Cached Background Processes. The Standard is 20. Setting it to 4 will save on available RAM & Battery. Since 20 processes are cached whether nor you have those apps open in the background or plan to use those apps. Like Force 4x MSAA, this setting will reset to it's default setting if your device is powered off or powered off & restarted. Including hot boot or hot reboot. To use it after that, you will need to set it again.
